Keeping time without internet connection

Questions & Help
1

I have a Homey Pro that I would like to automate the locking and unlocking of a small office building with Z wave technology since the tenants generally do not lock the building at the end of the day. I do not have my own internet service at the office building.

I have set up my Homey Pro and Zwave lockset using my residential internet and would like to install it at the office building with no internet.

If I have the doors opening and locking via a Homey Pro flow at certain times. Does this work without internet connection? If power goes out and is regained 2 hours later will it know the time to lock the doors? Is there a solution for this?

Thanks

The only solution is providing Internet access to Homey Pro. Without Internet it probably doesnā€™t get the time correct.

First of all, welcome to the Homey Community!

To make sure you are aware of the forum rules, please read the Welcome to the forum! post here.

Not sure, but if you can find a Atomic Time device that comunicates with Homey ?
Or sets your router to the correct time ?

Do you have an example and where to configure Homey to use that time? Afaik that isnā€™t possible to configure.

I didnā€™t find any documentation how Homey Pro would get time from a local network source.

Iā€™m new to this so I donā€™t no either.

I just used the flow chart to unlock at 6:30 am and to lock at 8:30 pm

I not sure but an internet search for the Schlage Connect dead bolt which is battery powered says it keeps time but the time has to come from somewhere, which I suspect is through the Homey Pro internet connect upon set up.

But I donā€™t know what happens when you change batteries and you donā€™t have an internet connection

Hi Geurt,

Because I canā€™t find any relevant info @ support.homey.app:

When Homey is being set up in the same timezone, with internet access:
for how long should the clock run correctly when Homey runs without internet? Even with some power cycles?

Is there any documentation known to you?

Athom markets ā€˜Everything localā€™, which means, to me, the internal clock should run fine without internet.

Homey Pro has no internal Clock with battery, so one powercycle and it is in best case behind by the # seconds for the reboot / power-outage. afaik you cant set the time for Homey without Internet after a boot.

Internet Down for some time after it has the correct Time from the Internet after the restart/boot is probably OK.

Ah I see. Itā€™s clock needs an internet connection at regular intervals.

Ok, never expected Homey to miss a basic thing like set time. I think every OS has itā€¦

Homeyscript maybe ?

11

pls tell me howā€¦
You need Internet to configure Homey scripts,
or an existing script with the Then card: ā€œStart Script with Argumentā€ and the Time in the Argument,

beside that there is no setTime function in HomeyScript.

In that case, Homey wonā€™t work at all anyway. It requires a working Internet connection.

So their advertising is false,

Always up ā€” even when your internet is down.
Homey Pro processes everything locally, so itā€™s always up, even when your internet is down.

I also only wanted to use Homey locally, or at least in the event of an internet outage, but no chance! I had a Homey Pro and also think Homey misleads buyers with its advertising promisesā€¦! I switched to Home Assistantā€¦ Much better options for less money :person_shrugging:t3:

maybe something for you too

But Homey does work when your Internet is down.

Internet down assumes you have Internet, but interrupted. ā€˜No Internet presentā€™ is not really the sameā€¦

Yeah reading skillsā€¦.

To the haters:

Robert responded to a case where the location has no internet at all. Homey will be useless then.

But your occasional internet outages shouldnā€™t be a problem.
